What is CPT
96150
?
96150 is a CPT code specifically designated for the assessment and diagnostic testing services within the realm of behavioral health. This code is typically utilized to capture the clinical activities associated with the evaluation and measurement of a patient's mental health status. This entry provides an overview of the clinical applications of the code, the necessary documentation expectations, and considerations specific to various payers. It is vital for providers to ensure that their clinical notes not only align with evidence-based interventions but also clearly outline treatment goals, the interventions utilized, and measurable progress made by the patient. In instances where the code is billed based on time, it is essential to include accurate start and stop times to substantiate the billed duration.
Documentation Tips
Effective documentation is crucial for billing CPT code 96150 accurately and ensuring compliance. When billing for time-based psychotherapy, it is necessary to document both the start and stop times of the session. Additionally, the documentation should include details about the therapeutic modality or the specific assessment instrument utilized, the clinical focus of the session, the patient's response to interventions, and a clear plan for follow-up. For any scored instruments used during the assessment, ensure that copies of completed tools are maintained in the patient's records. In the case of telehealth services, it is also important to document the patient's consent and the details of the platform used for the session. To enhance audit readiness, utilize consistent documentation frameworks such as SOAP (Subjective, Objective, Assessment, Plan) or DAP (Data, Assessment, Plan) structures.

Billing Examples
A practical example of using CPT code 96150 includes a clinician administering the PHQ-9 questionnaire to assess a patient's depressive symptoms. The clinician scores the instrument, documents the patient's responses, and files the necessary paperwork for billing purposes. Another scenario may involve the administration of standardized neuropsychological assessments, which are followed by comprehensive scoring and interpretation workflows. These workflows justify the use of assessment codes by demonstrating a structured approach to evaluation and treatment planning. Documenting the rationale for administering specific instruments and the outcomes will further support the billing process.
